Solution for Precision Cooling and Fluid Management Optimization in Immersion Cooling

1. An immersion cooling unit, comprising: an immersion tank; a coolant supply line to supply cooled coolant from a heat exchanger to the immersion tank, wherein the heat exchanger is configured to extract heat from heated coolant and transform the heated coolant into the cooled coolant; and a coolant return line to return the heated coolant from the immersion tank to the heat exchanger, wherein the immersion tank includes: a plurality of equipment compartments to contain a plurality of electronic devices respectively, one or more separator walls to separate any neighboring equipment compartments of the plurality of equipment compartments to prevent the cooled coolant or the heated coolant from circulating between any neighboring equipment compartments, wherein the separator walls are higher than other walls that compose the plurality of equipment compartments, such that the heated coolant that has exited from any of the plurality of equipment compartments at the top is prevented from entering an adjacent equipment compartment, and a heated coolant reservoir disposed around the plurality of equipment compartments, wherein subsequent to being supplied to the immersion tank, the cooled coolant enters the equipment compartments from a bottom of the equipment compartments, extracts heat generated from the electronic devices, and is transformed into the heated coolant, wherein the heated coolant in the equipment compartments exits the equipment compartments at a top of the equipment compartments and enters into the heated coolant reservoir, wherein a liquid level in the heated coolant reservoir is below a height of the plurality of equipment compartments, such that the heated coolant in the heated coolant reservoir is prevented from circulating back into any of the plurality of equipment compartments, and wherein the heated coolant in the heated coolant reservoir is returned to the heat exchanger via the coolant return line.
